RAI LWAY-RAIL FASTENING.

SPECIFILC'ATION forming part of Letters Patent No. 461,717, dated October 20, 1891.

Application filed January 2'7, 1891. Serial No. 379,284. (No model.)

To all whom it` 'lnctyconccrm Be it known that l, LEWIS SCOFIELD, Sr., a citizen of the United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented certain new and useful Improvements in Railway-Rail Fastenings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

` combination of parts, substantialiyas will be hereinafter described and claimed.

ln the accompanying drawings, illustrating` my invention, Figure l is a cross-section of my improved railway-rail fastening, its several parts being shown as arranged 1n operative connection with a rail and tie. Fig. 2 is a top plan view of the samein partial section on the line ,fr of Fig. l. Fig. 3 is a reverse plan view of the metallic strap orsupport on which the rail islseated. Fig. 4; is a reduced perspective View of the clamping-piece for one side of the rail. Fig. 5 is a reduced perspective view of the clamp for the other side of the rail.

Similar letters of reference designate corresponding parts throughout all the different figures of the drawings.

A denotes a portion of atie for rails, which may be a metal plate or metal tie or anyother suitable kind of tie or sleeper.

B designates a U-shaped or right-angled metallic loop lor strap arranged in reverse position upon the bed-plate or tie A and transversely to the rail, which is to be supported or seated upon the top of the metalllc strap B, it serving, therefore, as a rest to uphold the rail. This support B is in reality a channeliron having a flat upper surface, and itis provided with anges l) b, which rest upon the tie A, said lianges being perforated at b b to permit the passage therethrough of certain bolts, byv means of which the angular support is secured lixedly and immovably upon the tie.

Dl Dl designate the bolts whichgfasten the support B to the tie A. They are of any suitable and ordinary construction and are provided with heads and also with inclined or beveled shoulders cl2 between the heads and the main cylindrical stems of the bolts, said inclined shoulders cl2 being cut square, as shown in dotted lines in Fig. 3, so that they may enter correspondingly-inclined square grooves or offsets in the under sideof the tie A round about the perforations therein through which the said bolts pass. This construction prevents the bolt from rotating and enables its head to be kept firmly in place. The bolts D D pass through the perforations h and are provided with nuts d', which are screwed firmly upon the ends of the said bolts; also nut-locks are provided consisting of flat perforated washers E, located between the nuts d and the upper faces of the tianges b b, which Washers have flanged edges e, adapted to be turned up closely against the nut CZ after the latter has been screwed firmly in place. (See Figs. l and 2.) Furthermore, the support or rest B is provided With perforations in the upper part thereof to permit the passage of bolts D D, constructed similar to the bolts D D', which bolts D serve to keep the clamps in firm position upon the upper side of the rest B, and thus secure therail in place.

C denotes an example of rail which in the present form of the invention it is designed to secu re in place. It has a Web c, bottom flanges c c', and upper flanges c2 and c3. On one side of this rail is a side clamp F, which consists simply of an angular plate of suitable size and shape, it having a form which permits it to rest partly upon the fiat surface of the upper side of the rest B and partly upon one of the base-flanges c of the rail, its edge being close up against the web c of the rail, as shown in Fig. l. The clamp F is shown in perspective in Fig. 4 and said clamp is perforated, and through its perforation passes the securing-bolt D, which has its upper screw-threaded end provided with a nut d, between which nut and the upper face of the clamp F is located a perforated Washer TOO E, Whose iianged edge e is adapted to bend up closely against the edge of the nut CZ after the latter has been screwed firmly into place, the inner edge of said Washer resting neatly7 and tightly against the shoulder f,formed on the upper side of the clamp F. NVhen the bolt D has been located in position and its nut been tightly screwed, the clamp F will bear Iirmly and Wit-h a strong grip upon the flange c of the rail, holding it tightly. On the other side of the rail there is another clamp, which is shown in reduced perspective in Fig. 5. This clamp has the vertical portion G, which rests close against the side of the rail-web o and has its upper end bearing neatly against the side of the upper railiange c2. This clamp is likewise made integral with the inclined part G', which fits neatly against the upper side of the other base iiange c of the rail, and said part G is integral With the remainder of this clamp, which has a iirm'seat upon the upper face of the rest B. Thus it will be seen that the clamping device G holds the rail rmly upon the rest on the one side and that the two clamps F and G together hold the rail very tightly between them and clamp it securely and rig idly upon the rest B. The fiat portion of the clamp G is perforated to permit the passage through it of another bolt D, which has a nut CZ, which is kept in place by the locking device consisting of the Washer E, having fiange e, one edge of the washer fitting neatly against the shoulder g, formed on the upper side of the clamp. The bolts D D, having the inclined sections which are arranged at right angles to each other on a square in order to iit into the square countersinks baround the perforations b2 in the upper part of the rest B, are kept from rotating and held fixedly, and these bolts when connected with the locknuts with which they are provided keep the clamps F and G Very firmly fixed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a railway-rail fastening, the combination, with the rest B and rail C, of the clamp F. having shoulderf, the clamp G, having in elined part G and shoulder g, and the bolts D D, having inclined sections arranged on a square to fit into correspondingly-shaped recesses b3 in the rest B aud the locked nuts d rl.

In testimony whereof I aiiix my signature in presence of two Witnesses.
